Strap for Black Bay 31 S&G / Black / Bracelet

The lug width of the Tudor Black Bay One 79603-0001 is 16mm. This measurement corresponds to the distance between the case attachment pins and is essential for selecting compatible straps. A 16mm strap inserts into the lugs without play and requires no adaptation.

There is no universal choice. Alligator is ideal for those who appreciate water resistance and the natural grain that echoes the diver heritage of the model. Vegetable-tanned leather is perfect for those who desire a patina that evolves over time. Rubber is the minimalist and sportive solution. Shell cordovan is for the purist who does not fear accidental water exposure and appreciates superior structural rigidity.

The strap is secured by two threaded pins that pass through the case lugs. Use a spring bar tool to gently lift the pin and release the old strap, then insert the new strap into the lugs until it clicks into place. Ensure the pin is fully seated in the lugs before wearing the watch.

Yes, any 16mm strap is compatible with the Tudor 79603-0001. Aftermarket straps allow you to personalise the watch's appearance with different leathers, colours and finishes according to your taste. They provide the same reliability as original straps if crafted artisanally with quality materials.

A high-quality leather strap typically lasts 3–5 years with daily wear, varying depending on the type of leather and conditions of wear. Alligator is more durable (5–7 years), shell cordovan can last beyond 7 years, while calf leather requires more frequent replacement if exposed to intense weather. Regular maintenance (gentle cleaning and drying) extends the strap's lifespan.
